Specification of Letters Patent No. 8,101, dated May 20, 1851.

' To all whom it ma'yconcern Be it known that I, ROBERT Jonson, of

Holly I-Iall YVorks, near Dudley, in the county of Stafford, England, have invented Improvements in Fireplaces for the Com-.

bustion of Coal or other Proper Fuel and for Warming Apartments; and Ido hereby Figure 1 of the drawings is a front view.

Fig. 2 a vertical section and Fig. 3 a horizontal section of one of my improved stoves.

The same letters refer to similar parts in each figure.

A is a square plate of front of the stove.

B is a circular metallic reflector surroundingthe fire.

C is the grate for containing the fuel.

D is the register or damper.

E is the back of the grate.

F is a metal plate or ash guardperforated with apertures for admitting air under the fire. Its principal olfice is to prevent the ashes and coals which may drop fromithe grate from falling upon the reflector.

G is a frame or. skeleton connecting the front plate A with the back E. The grate (l is supported back E.

H is a sliding plate to which the reflector is hinged at I. The slide H is supported and guided by four rollers K, K, K, K, turning in a frame fixed on the skeleton G and better seen in Fig. 4: which shows a portion of the skeleton G the slide H; rollers K, K, K, K, hinge I and a portion of the back of the reflector B. Fig. 5 shows asection of theslide Htogether with two of the rollers K, K.

Instead of allowing the ashesto fall through the grate on the hearth it ismore convenient to place under the grateC an ash box which may be made large enough to hold a considerable quantity of ashes and will consequently only require occasional metal forming the by being screwed to the when access tothe chimney is required the reflector B is drawn forward until the stop. S on the slide H meets the skeleton G. The reflector is then swung around on the hinge I. a A i c L is a bar or blade which is fixed to the reflector and is guided into its place by the roller M. A small pan may be placed under the front edge of the reflector to receive any dust or coal which mayfall on the reflector. Owing however to the reflector being notched out below the fire and having an ash guard F applied to it and the front of thegrate, the greater portion of the dust and ashes will fall into the ash box and by means of the ash guard be effectually prevented from entering the apartment in.

which the stove is fixed.

When the stove is in use the fire appears completely surrounded by the reflector which thus throws out into the apartment nearly the whole of the radiant heat of the fire. The reflector being made of one piece of cast iron completely surrounding the fire ismuch easier made than a reflector which only partially surrounds the fire or which is made in separate pieces because these pieces are very apt to warp and become twisted and deformed while in the act of cooling after they are cast which is not the case with the reflector cast in one piece which completely surrounds the fire. I do not however confine myself to the use of cast iron as the material of the reflector for Wrought iron emptying. When it is to be emptied or or steel or brass or othersuitable material or materials may be employed.

The reflector shown in the drawing is a portion of a paraboloid the section being a portion of a parabola. The sectional form may be varied and a portion of a sphere or a cone or hyperboloid or hell shaped figure may be employed. The form of the front view may also vary and instead of being circular may be oval or rectangular. In place of hanging the reflector on a hinge it may be rendered movable by being supported onwheels or in any other convenient manner.

Instead of making the whole of the reflector movable only a portion of the upper part over the fire may be made movable so as to form a door for obtaining access tothe chimney but the principal part of the reflector should still completely surround the fire when viewed in front and should be formed of one piece of metal so that it may not be liable to warp in the casting which would be the case if it were completely out through at any part. The lower part of this fixed reflector should be notched as already described with regard to the movable reflector so as to embrace the ash guard. The ash box when used may be made shallow so as to enable it to be drawn out under the reflector which for this purpose may be fixed with its lower edge a few inches from the floor or hearth.

I do not claim as my invention a reflector made to partially surround the fire, but what I claim as my improvement is- The extension of the curved refiector entirely around the fire grate in combination with having an opening through it, immediately under the fire grate, for the passage of the ashes as specified.

and the extension of the reflector under or below the grate essentially as explained, I claim the ash guard F, the same being applied in manner and for the purpose as set forth.

3. And in combination with the reflector B and its sustaining frame, I claim the hinged slide H and the sustaining rollers K, K, K, K, or their mechanical equivalent; the same being applied so as to enable the reflector to be moved outward for the purpose of providing easy access to the chimney or for convenience of removing the ashes whenever such may be deemed necessary.
